云南马龙苍龙山Mo-Ni多金属矿床赋存于下寒武统筇竹寺组石岩头段。矿床由上、下2个Mo-Ni多金属矿层组成,分别赋存于石岩头段上部和中、下部。矿层呈薄层状产出,延伸稳定,矿层共(伴)生元素多。矿层受构造、地层、岩性及岩相控制明显。矿石具纹层状构造。矿石U/Th比值3.37~14.29,平均8.64,表明受到较强的热液活动影响。综合地质特征和微量元素分析资料,认为马龙苍龙山Mo-Ni多金属矿与广泛发育的华南寒武系Mo-Ni层具有相似的成因机制。不同的是本区发现两层Mo-Ni矿层,值得进一步深入研究。 The Malong Canglongshan Mo-Ni polymetallic deposit in Yunnan Province occurs in the headrace of Shiyamiji Formation in the Lower Cambrian Qiongzhusi Formation. The deposit consists of two upper and lower Mo-Ni polymetallic ore layers, which are respectively located in the upper part, the middle part and the lower part of the Shitan head section. The ore layer is thinly layered and has stable extension. There are many elements in the ore layer. The mine is controlled by tectonics, strata, lithology and facies. Ore with layered structure. The ore U / Th ratio is 3.37 ~ 14.29, with an average of 8.64, indicating that it is affected by strong hydrothermal activity. According to the comprehensive geologic characteristics and trace elements analysis data, it is concluded that the Mo-Ni polymetallic ore of the Marongong Mountains has a similar genetic mechanism with the widespread southern Cambrian Mo-Ni layer. The difference is that the discovery of two Mo-Ni deposits in this area deserves further study.
